A compressed-air compressor, the compressor having a cylinder; a piston mounted to slide along the cylinder and define, inside the cylinder, a variable-volume compression chamber; and an actuator assembly connected to the piston to impart to the piston a reciprocating travel, along the cylinder, between a top dead centre position and a bottom dead centre position; the actuator assembly having a belt drive; and the cylinder having a vent hole formed, at most, at 60% of the travel of the piston, measured from the top dead centre position.
